[0002] The water thermal management system plays an important role in new energy vehicles. Through the circulation of the cooling liquid, it can dissipate heat from the heat-dissipating components in the vehicle and use the heat from the heat-dissipating components to heat the components that need to be heated. However, the existing water thermal management system mainly focuses on heat dissipation of the heat-dissipating components, and the function is relatively single, and the utilization rate of heat energy is low. At the same time, some components that need to be heated in the vehicle also need to be additionally provided with heating components and consume additional electric energy for heating. For example, some existing vehicles are provided with cup holder heating function. The cup holder heating function can provide heating and insulation function for the tea and drinks of the driver and passenger, so that the driver and passenger can drink warm and comfortable tea and drinks at any time, which helps to improve user experience and enhance product power. However, the cup holder heating on the market usually uses an additional semiconductor refrigeration / heat sheet to achieve it, and the heat energy in the water thermal management system cannot be effectively utilized.
[0003] Therefore, it is necessary to provide a new technical scheme to overcome the deficiencies of the prior art. CONTENT OF THE INVENTION

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0027] This application provides a thermal management system for heating items or parts to be heated. The thermal management system includes a controller 1, a hydrothermal circuit 5 for dissipating heat from the controller 1, a heating container 2, and a control valve 3. The heating container 2 is connected to the hydrothermal circuit 5 and heat exchange can occur between them. The control valve 3 controls the on / off connection between the hydrothermal circuit 5 and the heating container 2, thereby controlling whether the heat from the hydrothermal circuit 5 heats the heating container 2.
[0028] The thermal management system provided in this application transfers the heat generated by the controller 1 that needs to be dissipated to the heated container 2 through the water-heat circuit 5 to heat the heated container 2, thereby realizing the utilization of waste heat and achieving heating of the heated container 2 without consuming additional electrical energy.
[0029] Please see Figure 1 As shown, in this embodiment, the thermal management system includes a refrigeration unit installed in the vehicle's front compartment. The water-heating circuit 5 sequentially connects the refrigeration unit, controller 1, control valve 3, and the heating container 2 to form a coolant circulation loop. The coolant is cooled in the refrigeration unit to form a cryogenic liquid. The cryogenic liquid flows through the controller 1, absorbing the heat generated by the controller 1, thus lowering the temperature of the controller 1 and achieving cooling and heat dissipation. As the cryogenic liquid absorbs the heat from the controller 1, its temperature rises, becoming a high-temperature liquid. The high-temperature liquid flows through the control valve 3 to the heating container 2, where its heat is transferred to heat the container. After passing through the heating container 2, the high-temperature liquid flows back to the refrigeration unit for cooling, and the cycle continues. Because the high-temperature liquid transfers some heat to the heating container 2, the liquid temperature decreases to some extent, which can reduce the cooling power of the refrigeration unit and help increase its service life.
[0030] Please continue reading. Figure 1As shown, the control valve 3 is connected to the hydrothermal circuit 5 and is located between the controller 1 and the heating container 2. In this embodiment, the control valve 3 is a three-way valve, specifically, for example, an electromagnetic three-way valve. The control valve 3 can control the coolant in the hydrothermal circuit 5 to flow sequentially through the controller 1, control valve 3, and heating container 2, and then back to the refrigeration device, forming a large circulation loop; it can also control the coolant in the hydrothermal circuit 5 to not flow through the heating container 2, so that after passing through the controller 1 and control valve 3, the coolant flows back to the refrigeration device, forming a small circulation loop. Thus, when the heating container 2 needs to be heated, the coolant flows through the heating container 2; when the heating container 2 does not need to be heated, the coolant does not flow through the heating container 2. In other embodiments, the components through which the hydrothermal circuit 5 flows are not limited to those described above; it can also be connected to other components that need heat dissipation or heating.
[0031] In this embodiment, the heating container 2 is a milk warmer used to warm milk for infants. In other embodiments, the heating container 2 can also be a container for heating tea, beverages, or other foods. For infant milk, the optimal temperature is around 45°C. Similarly, for other beverages or foods, a temperature of around 45°C is also suitable, providing warmth without causing burns. The coolant in the hydrothermal circuit 5 typically reaches temperatures exceeding 50°C, capable of heating the heating container 2 to around 45°C. In some usage scenarios, the opening of the control valve 2 can be adjusted to distribute the proportion of coolant flowing through and not flowing through the heating container 2, thereby regulating the heating temperature of the heating container 2. The heating container 2 can transfer heat to the food, beverages, etc., inside through direct contact. In some embodiments, the heating container 2 can also transfer heat via a water bath, i.e., the heating container 2 contains clean water, and the baby bottle or other beverage bottle is placed in the water within the heating container 2 for heat transfer.
[0032] In this embodiment, the controller 1 is the vehicle's entertainment domain controller. In this embodiment, the entertainment domain controller and the heating container 2 are arranged in a close area. By transferring heat from the entertainment domain controller to the heating container 2, the transfer path is short, the system layout is convenient, and heat loss is minimal. Of course, in other embodiments, the controller 1 is not limited to the entertainment domain controller; it can be other controllers. Please refer to [link to relevant documentation]. Figure 2As shown, in this embodiment, the controller 1 includes a main body 11 and a protective plate 14 disposed outside the main body 11. The main body 11 has an internal flow channel connected to an inlet pipe 12 and an outlet pipe 13. The main body 11 is connected to the hydrothermal circuit 5 via the inlet pipe 12 and the outlet pipe 13. Coolant in the hydrothermal circuit 5 can flow into the main body 11 through the inlet pipe 12 to dissipate heat from the main body 11, and then flow out of the main body 11 through the outlet pipe 13, returning to the hydrothermal circuit 5. The protective plate 14 is disposed on the outside of the main body 11 to protect it.
[0033] Please refer to the following: Figure 3 As shown, the thermal management system includes a heat exchanger connected in series downstream of the controller 1, with the heated container 2 in contact with the heat exchanger. The heat exchanger downstream of the controller 1 transfers the heat carried by the coolant flowing through the controller 1 to the heated container 2 in contact with it, thereby heating the heated container 2. In this embodiment, the heat exchanger includes a heat exchange plate 4 mounted on the controller 1, with a flow channel within the heat exchange plate 4 through which the coolant in the water-cooled circuit 5 flows. The heat exchange plate 4 is also known as a water-cooled plate, and typically has tortuous flow channels to achieve efficient heat exchange. The heat exchange plate 4 is used for heat exchange with the heated container 2. It is not limited to... Figure 3 The plate shown can also be cylindrical or similar, designed to facilitate large-area contact with the heated container 2 and enhance heat exchange. In this embodiment, the heat exchange plate 4 is mounted on the protective plate 14. The heat exchange plate 4 has a flow channel for the coolant in the water supply circuit 5, and this flow channel communicates with the internal flow channel of the controller 1. In this embodiment, the control valve 3 includes a three-way valve, and the heat exchange plate 4 is connected to the outlet pipe 13 via the three-way valve. The heated container 2 contacts the heat exchange plate 4; specifically, the heated container 2 can be directly positioned above the protective plate 14. In this embodiment, the protective plate 14 includes an upper protective plate mounted on the upper surface of the main body, and the heat exchange plate 4 is mounted within the upper protective plate to be integrated with the controller 1. This reduces the number of loose parts and facilitates overall disassembly and maintenance.
[0034] Please refer to it again. Figure 1 and Figure 2As shown, during use, the entertainment domain controller is connected to the vehicle's thermal management circuit. The vehicle's thermal management circuit allows the coolant from the three-electric system to flow through the entertainment domain controller, cooling it. The inlet port of the control valve 3 is connected to the entertainment domain controller, and one of its two outlet ports is connected to the heat exchange plate 4, which exchanges heat with the heated container 2. The other outlet port is connected to the return water heat circuit 5 via a pipeline. The coolant exiting the entertainment domain controller is controlled by the control valve 3. When the outlet port of the control valve 3 connected to the heat exchange plate 4 is opened, the coolant can flow through the control valve 3 through the heat exchange plate 4 to heat the heated container 2. When the outlet port of the control valve 3 connected to the heat exchange plate 4 is closed, and the other outlet port is open, the coolant does not pass through the heat exchange plate 4 and the heated container 2, but flows directly into the front compartment thermal management system, without heating the heated container 2. The coolant in the water-heat circuit 5 comes from the front cabin thermal management system. The coolant coming out of the front cabin thermal management system has a low temperature. After passing through the entertainment domain controller, the coolant is heated. The heated coolant flows through the heat exchange plate 4 and exchanges heat with the heated container 2 set on the heat exchange plate 4 to heat the heated container 2.
[0035] This application also provides a vehicle that includes a thermal management system as described in any of the above.
[0036] As described above in the specific embodiments, the thermal management system provided in this application includes a controller 1, a heating container 2, a control valve 3, and a water-heating circuit 5. The heating container 2 is connected to the water-heating circuit 5, and heat exchange can occur between them. The control valve 3 controls the on / off connection between the water-heating circuit 5 and the heating container 2, thereby controlling whether the heat in the water-heating circuit 5 heats the heating container 2. That is, the heat generated by the controller 1 is transferred to the heating container 2 through the water-heating circuit 5 to heat the heating container 2, realizing the utilization of waste heat, improving the thermal energy utilization rate, and eliminating the need for additional electrical energy consumption.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
